BACKGROUND
On March 15, 2016, Council approved the plans and specifications for the FY 2016 - Pavement Preventative Maintenance & Resurfacing Project, and called for bids to be received on April 26, 2016.
The City's Street Preventative Maintenance (PM) & Resurfacing Program involves streets in relatively good condition where the application of the low cost slurry seal treatment is used to prolong the life of the pavement, and protect the city's original investment in rehabilitating or reconstructing the street. The PM treatment reduces the amount of water that can infiltrate the pavement structure, protects the pavement system, and slows the rate of deterioration.
Slurry seal is a mixture of water, asphalt emulsion, aggregate, chemical additives and polymer. The polymer provides better mixture properties. This year, staff will be using a special slurry seal called micro-surfacing. The primary difference between micro-surfacing and the slurry seal used in prior years is in how the emulsion cures. The asphalt emulsion used in micro-surfacing contains chemical additives, which allow it to break without relying on the sun or heat for evaporation to occur. Thus, micro-surfacing is an application that cures quicker than ordinary slurry seals. This will allow the street to be returned to traffic use much sooner than using the ordinary slurry seal. The micro-surfacing application will be made a...
